How to calculate drawer box size
This calculator finds the correct drawer box width by subtracting the total slide clearance from the cabinet opening width — ensuring the drawer slides smoothly within its opening.
How the calculation works
Drawer box width = Cabinet opening width − Total slide clearance.
Example
A 15-inch cabinet opening with 1-inch total slide clearance (1/2 inch per side): Drawer box width = 15 − 1 = 14 inches.

Pro Tips for Drawer Box Size
- Total slide clearance depends on your specific drawer slide hardware — check the manufacturer's spec sheet for the exact clearance required per side.
- Build a test drawer box or check hardware specs carefully before cutting a full set, since slide clearance requirements vary by slide type (side-mount vs. undermount).
Common Drawer Box Size Mistakes to Avoid
- Using a generic clearance assumption instead of the actual manufacturer specification for your chosen drawer slide hardware.
